BUTTON.

SPECIFICATIQN forming part of Letters Patent No. 312,936, dated February 24:, 1885.

I Application filed January 12, 1885. (No model.)

f0 aZZw/wm, it may concern.-

Be it known that I, JoHN H. WALKER, of WVaterbury, .in the county of New Haven and State of Connecticut, have invented a new Improvementin Buttons; and I do hereby declare the section shown in Fig. 2; Fig. 4, a sectional- View of the front and back of a button detached; Figs. 5, 6, 7, 8, 9, and 10, modifications of the bar.

This invention relates to an improvement in that class of buttons which are made to present a metal face with an opening through the center, by which the button may be secured by stitching to the garment, commonly called pantalocn-buttons. In the usual construction of these buttons they are made in two parts, one part called the front, and which forms the face of the button, and the other the back. The back is convex, or so as to give considerable thickness to the button. The edge of the back enters within a flange around the front, and then the flange closed upon the back to secure the parts together. Through the two parts is a central circular opening, and across this opening a bar has been arranged, in some cases made from wire, in others made from sheet metal, and doubled to present a rounded edge above, this bar being introduced between the front and back, and so as to cross the central opening. In some cases the bar hasbeen made as a part of the front or face; but in either case there is a very considerable space in the hole between the front and back. This space or annular opening within the central bar-button with the side or wall of the opening substantially closed and protected to prerior of the button, and also to prevent cutting the thread; and the invention consists in constructing the front and back each with a flange upon its inside around the opening, the diameter 0f the opening in both being substantially the same, and so that the two flanges will sub stantially meet each other and form a wall around the opening, combined with a bar extending across the said opening, as more fully hereinafter described.

The button is formed of the usual two parts, a representing the front, and b the back. Around the outer edge of the front is the usual flange, c, which is closed onto the back to secure the two parts together, and at thecenter is the usual semicircular concentric opening, (1. Around this opening the metal of the front is turned inward to form the flange 0. The back I) has a like opening at its center, and around that opening is an inwardly-turned flange, f, corresponding to the flange e on the front, the depth of the two flanges being such that they will substantially meet, as seen in Fig. 3, and so that when settogether, as seen in the said Fig. 3, the two flanges form substantially a close wall around the central opening.

The bar may be made in various wayssay, as by a straight piece of wire, 71, cut to the required length.

Toreceive the bar, one of the parts, either the front orback, may be both, are constructed with a notch, i, at two points diametrically opposite each other, and so that the piece of the bar being such that it cannot move longitudinally sufliciently far to bring either end Within the opening, and as indicated in Fig. 2.

Instead of making the bar from a straight piece of wire and depending upon its length to strike opposite points in the button, to prevent either end cntering the opening, and thereby escaping, it may be madewith a head upon each end, as seen in Fig. 5, and so that the two ends will lie against the inside of the flange around the opening in the button, the heads preventing longitudinal movement of the button; or it may be made in a ring shape with the bar bent diametrically across it, as seen in Fig. 6, the internal diameter of the vent such entrance of the needle to the intewire or bar may be laid therein, the length of ring corresponding to the flange around the opening in the parts and so as to surround the flange; or it may be made a half-ring, as seen in Fig. 7 or it may be made a tube, as seen in Fig. 8; or it may be struck from sheet metal, and so as to leave abar across the center, and the bar doubled, as seen in Fig. 9; or the end of the wire may be split, as seen in Fig. 10, the two parts turned to the right and left to form substantially a head on each end of the bar.

While I prefer to out the notch in the edge of the flange or flanges in the two parts to em brace and locate the bar, this need not be done in the process of forming the 'front and back; but in closing the two parts together the edge of the flange will strike the bar, and so that the flanges will be indented sufliciently to hold the bar in its diametrical position. In any case the flange of the two parts forms a wall so surrounding the opening of the button that there is no'interruption of the needle in its passage through the but-ton. Once entering the opening, the walls form a guide to insure its proper direction.

From the foregoing it will be understood that I do not claim, broadly, a button having the bar diametrically across its opening, or any particular construction of bar, many of the bars as heretofore constructed being adapted to this improvement.

I claim i 1. The herein-described button,consisting of the metal front a and back I), each constructed with a concentric opening, and with an inter- 'nal flange around the opening in each part to form a wall around the central opening when the two parts are set together, combined with a bar diametrically across the opening and between the two parts, substantially asdescribed.

2. A bar-button composed of the front A and back B, each constructed with a concentric opening, and with an internal flange around the opening in each part to forma wall around the central opening when the two parts are set together, the bar arranged diametrically across the said opening, and constructed to take a bearing against the inner side of the flange, substantially as described, and whereby longitudinal movementof the bar will be prevented;
